AWS Solutions Architect
AWS Foundations
Certification-aligned AWS fundamentals: account structure, global infrastructure, identity, security, and core cloud mental models.
foundation
AWS Account Model
Build the mental model for AWS accounts as security, billing, ownership, and blast-radius boundaries before studying individual services.
foundation
AWS Global Infrastructure
Understand Regions, Availability Zones, edge locations, and global services as the physical map behind AWS architecture decisions.
foundation
Shared Responsibility Model
Learn how AWS and customer responsibilities shift across infrastructure, managed services, security, data, identity, and configuration.
foundation
IAM Foundations
Understand AWS IAM principals, policies, roles, permissions, and least privilege as the access-control base for AWS architecture.
foundation
IAM Users vs Roles
Learn when AWS access should use IAM users, IAM roles, federation, and temporary credentials instead of long-lived access keys.
foundation
Identity Policies vs Resource Policies
Understand how AWS identity-based policies and resource-based policies work together for same-account and cross-account access decisions.
foundation
VPC Networking Model
Build a first-principles model of AWS VPC networking, including subnets, routing, gateways, security groups, NACLs, and private connectivity.
foundation
Public vs Private Subnets
Understand what makes an AWS subnet public or private, how route tables and gateways decide reachability, and where workloads should live.
foundation
Security Groups vs NACLs
Compare AWS security groups and network ACLs as stateful resource-level firewalls and stateless subnet-level guardrails.
